There is currently no known cure for Parkinson's disease but motor symptoms such as tremor, muscle rigidity and slowness of movement may be relived by medications that restore the deficiency of dopamine by increasing or maximising the level of dopamine in the brain (dopamine replacement therapy). There are two types of medication that can be used, those that can be converted into dopamine by neurons and those that mimic the role of dopamine and are able to effectively stimulate reception of dopamine by neurons within crucial motor areas by causing neurons to react as they would to dopamine.

As people experience motor symptoms and the inability to perform voluntary movements this can cause patients to become depressed and experience mental health problems also as a result of the decrease levels of dopamine being released.

# data[].attributes.body
There are 4 key motor symptoms of Parkinson's disease. These include tremors which involves continuous, involuntary shaking of the body, Bradykinesia which is slowness of voluntary movement, particularly when initiating and executing movement, muscle rigidity which is when the muscles seem unable to relax and are tight even when at rest and finally postural instability which involves difficulty maintaining an upright posture and a steady balanced condition. Some non-motor symptoms include speech problems which involves in a change in verbal fluency as well anosmia which is a decreased or loss of smell.

Parkinson's disease is a neurodegenerative disease that causes a degeneration and loss of neurons within the substantia nigra, which is a structure located within the basal ganglia in the midbrain in the central nervous system. As the neurons in the substantia nigra produce the neurotransmitter dopamine which carries messages that allow smooth, coordinated functions of the body's muscles and movement, so when the substantia nigra is diseased or damaged, the amount of dopamine available is reduced.

A possible cause of Parkinson's is a decrease of dopamine in the subtantia nigria due to neurons gradually dying. Another cause is defective receptors

# data[].attributes.body
Parkinson's disease is a neurodegenerative disease that causes the amount of dopamine available in the subtantia nigra to reduce as neurons gradually die. It is referred to as a neurodegenerative disease because it is in the brain and symptoms progressively get worse over time.
